Risk assessment specialist Riskstop has issued a warning to landlords regarding potential new electrical, fire, and insurance risks associated with plug-in solar panels in rented properties. The firm states that property owners need to understand the installation process and whether current electrical systems can support the technology.
Plug-in photovoltaic (PV) solar panel systems have been legal for purchase and use in the UK since 27 August 2026, following government changes. These smaller systems, already in use in parts of Europe, are designed to make solar power accessible to flats and properties not suitable for conventional roof-mounted panels.
Johnny Thomson, Riskstop's head of strategic planning, noted that while plug-in systems are designed for householder installation and connect directly to a standard electrical socket, they are not risk-free. He explained that they introduce hazards similar to traditional PV systems, along with risks from user installation, product compliance, mounting, and interaction with existing electrical circuits.
Riskstop advises that the condition and suitability of the electrical installation, product compliance, and equipment protection must all be assessed. Landlords may also need to check if notification to the relevant network operator is required. Secure mounting against weather for panels on balconies, walls, or terraces is also highlighted, alongside potential requirements for landlord or freeholder consent, planning permission, and compliance with insurer conditions.
